Systems and Methods for Indicating Ultraviolet Sanitization

Abstract:

In an example, a protective assembly for visually indicating ultraviolet (UV) sanitization of an area is described. The protective assembly comprises a retrofitted protective bumper attachable to one or more surfaces in the area such that the retrofitted protective bumper covers at least a portion of the one or more surfaces. The retrofitted protective bumper comprises a photochromic plastic material that, when exposed to UV light, changes from a first color to a second color that is different from the first color and that is visible under ambient lighting conditions.
